Change iPhone colors through Settings, not a factory reset
You can change how your iPhone looks by adjusting color filters, display settings, and accessibility features built into iOS. These changes affect the entire screen — text, icons, photos, everything — without erasing your data or requiring you to restart your phone. The most common reasons to do this are to reduce eye strain, improve readability, or accommodate color blindness.
The fastest route is Settings > Accessibility > Display & Text Size, where you'll find color filters and contrast adjustments. You can also reach some of these same tools through Settings > Display & Brightness if you want to change overall brightness or enable Dark Mode. Changes take effect when ready and you can turn them off just as quickly.
Key Takeaways
- Color Filters in Accessibility let you shift the entire display toward warmer tones, grayscale, or specific color corrections for color blindness.
- Dark Mode inverts bright whites to dark backgrounds across most apps, which many people find easier on the eyes in low light.
- Increase Contrast and Reduce Transparency both live in Display & Text Size and make text and icons stand out more sharply.
- You can create a Shortcut to toggle these settings on and off with one tap, so you don't have to dig through Settings each time.
Enable Dark Mode for a darker overall appearance
Dark Mode changes the iPhone's interface from light backgrounds with dark text to dark backgrounds with light text. This affects your home screen, Settings app, Messages, Mail, and most built-in apps. Third-party apps like Instagram or Twitter will also switch to dark if the app's developer built that feature in.
Go to Settings > Display & Brightness and tap Dark. Your phone will switch when ready. If you want Dark Mode to turn on automatically at sunset and off at sunrise, tap Automatic instead of Dark, then set your preferred schedule under Options.
Dark Mode does not change the color of photos, videos, or images inside apps — only the interface around them. If an app has its own dark mode setting separate from iOS, you may need to turn that on separately within the app itself.
Use Color Filters to shift the display toward warmer or cooler tones
Color Filters let you explore a tint across your entire screen. The most popular filter is Warm, which shifts the display toward yellow and orange tones to reduce blue light in the evening. Other filters include Grayscale (black and white only), Deuteranopia, Protanopia, and Tritanopia (three types of color blindness correction), and Red/Green and Blue/Yellow filters.
To turn on Color Filters, go to Settings > Accessibility > Display & Text Size > Color Filters and toggle the switch on. Then tap the filter type you want. You can adjust the intensity with the slider below — move it left for a lighter effect, right for a stronger one. The change happens in real time as you move the slider, so you can see exactly how it will look.
If you use a specific filter every evening, you can automate it. Go back to Color Filters, tap Schedule, and set the time you want it to turn on and off. Your iPhone will explore the filter automatically at those times.
Increase Contrast to make text and icons sharper
Increase Contrast makes text bolder and icons more defined by adding darker outlines and reducing transparency effects. This is useful if you find the default display hard to read or if you have low vision.
Open Settings > Accessibility > Display & Text Size and toggle on Increase Contrast. The change is when ready. You can also toggle on Reduce Transparency in the same menu — this removes the frosted-glass effect from Control Center and Notification Center, making backgrounds more solid and text easier to read.
Both of these settings work together. You can use Increase Contrast alone, Reduce Transparency alone, or both at the same time. There is no performance cost to either one.
Create a Shortcut to toggle color settings on and off quickly
If you switch between color settings throughout the day — for example, turning on a warm filter at night and off in the morning — you can create a Shortcut that does this in one tap instead of navigating through Settings each time.
Open the Shortcuts app (it comes built into iOS). Tap the + button to create a new shortcut. Search for and add the action Set Color Filters. Choose which filter you want (Warm, Grayscale, etc.) and whether you want it on or off. Tap Done, then name your shortcut something like "Warm Filter On" or "Warm Filter Off".
Once you've created the shortcut, you can run it from the Shortcuts app, or add it to your home screen as an icon. You can also ask Siri to run it by saying "Hey Siri, [shortcut name]". Create multiple shortcuts — one to turn the filter on, one to turn it off — so you have both options available.
Use Night Shift to reduce blue light in the evening
Night Shift is a built-in feature that automatically warms your display in the evening by reducing blue light. It is different from Color Filters — Night Shift is gentler and designed specifically for sleep, while Color Filters give you more control over the exact color shift.
Go to Settings > Display & Brightness > Night Shift and toggle it on. By default, it turns on at sunset and off at sunrise based on your location. To set a custom schedule, tap Schedule and choose Custom, then enter the times you want.
You can also adjust how warm the display gets by dragging the slider at the bottom of the Night Shift menu. Move it left for a cooler effect, right for a warmer one. Night Shift and Color Filters can both be on at the same time, though that may look very orange.
Adjust text size and bold text for easier reading
If the text on your iPhone is too small to read comfortably, you can make it larger without changing anything else on the screen. Go to Settings > Accessibility > Display & Text Size and drag the slider under Larger Accessibility Sizes to the right. The preview text at the top of the screen will show you how large it will be.
You can also toggle on Bold Text in the same menu to make all text thicker and darker. This requires your iPhone to restart, so tap Continue when prompted and wait for your phone to boot back up. Bold Text and larger text work together — you can use both at the same time.
Frequently Asked Questions
Can I use Dark Mode and Color Filters at the same time?
Yes. Dark Mode changes the interface background from light to dark, and Color Filters add a color tint on top of that. You can have Dark Mode on with a warm color filter, for example, and they will both explore together.
Does Night Shift do the same thing as Color Filters?
They are similar but not identical. Night Shift is designed to reduce blue light before bed and turns on automatically at sunset. Color Filters give you more control — you can choose grayscale, color blindness corrections, or a specific warmth level. You can use both, but Night Shift alone is usually enough for most people.
Will changing colors drain my battery faster?
No. Dark Mode may use slightly less battery on newer iPhones with OLED screens because dark pixels use less power, but the difference is small. Color Filters, Night Shift, and text size changes have no meaningful impact on battery life.
Can I change the color of individual apps?
No. The color settings in iOS explore to the entire system — you cannot change just Mail to dark mode while keeping Messages light. However, many apps like Gmail, Twitter, and Spotify have their own dark mode settings inside the app that you can turn on separately.
What if I want to turn off all these color changes at once?
Go back to each setting and toggle it off: Dark Mode in Display & Brightness, Color Filters in Accessibility, and Night Shift in Display & Brightness. Or create a Shortcut that turns them all off with one tap, as described above.
